HD220 Dual Output Programmable Humidity Controller
Version 1.2 (June, 2018)
1. Overview
This is a dual-output humidity controller with 8 programmable steps. It contains
one humidity sensor and two independent outputs. One output is for humidifier
and the other is for dehumidifier. The humidity control can be programmed to
vary with different time step setting. Up to 8 humidity-time steps covering 33
days can be programmed. It can be used for tobacco dehydration, sausage
curing, etc. By using both humidifying and dehumidifying, the humidity ratio can
be controlled at a specific value regardless of whether it is in dry or wet
environments.
This controller is a plug-n-play device. No extra wiring is needed for the
humidifier or dehumidifier. Both humidifying and dehumidifying control modes
contain simple on/off operation; they are similar to a mechanical humidistat but
with much higher precision due to adjustable hysteresis band, precise sensor
and digital read out.
Different operation humidity ranges of the two outputs can be set separately.
Once the dehumidifying range is set, the controller program will automatically
limit the humidifying range to prevent both outputs from being turned on at the
same time.
This plug-n-play humidity controller is designed for high relative humidity
(>85%) and condensing environments, where a slight drop in temperature may
cause condensation and could damage other humidity sensors. This controller
equipped with one of the most robust humidity sensors on the market. It can be
fully recovered even immersed in water.
Wireless network connection capability is available in HD220-W. User can
access humidity data and parameter settings of the controller from their smart
phones or tablets. AuberSmart App is available on both iOS and Android
platform. For details, please check the supplementary manual.

4. Basic Operation
Here are the basic operating procedures to use this controller. To fully
understand the functions on this controller, please read the entire manual.
1) Connect the humidity sensor to the sensor socket that is located on the
bottom of the controller. Please check the alignment of the slot on the plug with
the key on the socket. (See section 12 for details.)
2) Plug the controller’s power cord to a wall outlet.
3) Set up the program and system parameters. Please read the rest of this
manual for details.
4) Connect the humidifying and dehumidifying devices to the output sockets on
this controller.
5) Press START key to start running the program.
5. Mode Selection
This controller has 5 different modes: program run, program hold, program
stop, parameter setting, and programming mode. Before powering on the
controller, please connect the sensor cable to it. If no sensor is connected, the
controller will show error code “Err”, indicating no sensor is detected.

Program Running: The controller executes the saved program. The green
indicator RUN is lit, and the timer is running. The display window should show
the current humidity reading. The controller will send power to its
humidifying/dehumidifying outlets to regulate humidity. When the program is
running, press PAUSE key will put the controller to Program Hold mode.
Program Holding: Controller pauses the time but it still regulates the humidity
at the current set value. The RUN indicator is off. The display window flashes
between the measured humidity value and “Hold”. To resume the program,
press START key. To completely stop the program, hold the STOP key for 4
seconds.
Program Stop: The execution of the program is terminated. Controller outputs
are deactivated and timer is also stopped. The RUN indicator is off. The display
window flashes between the measured humidity value and “Stop”. To start the
program, press the START key. The controller will start regulating the program
from the first step.
Programming Mode: Review and edit humidity set value and set time for each
steps. When the controller is in Program Run, Hold, or Stop mode, press SET
key to enter the Programming mode. Please see figure 4 for details.
Parameter Setting Mode: Review and edit system parameters. When the
controller is in Program Run, Hold, or Stop mode, hold the SET key for 2
seconds to enter the Parameter Setting mode. Please see figure 3 for details.
6. Parameter Setup
Please see Table 2 for a list of parameters and see Figure 3 for the flow chart of
how to set the parameters. Please note that parameters will remain unchanged
unless you press set key to confirm the change.
Press and hold the SET key for 5s to enter the parameter settings. Top display
shows the parameter name and bottom display shows the current value or option
for this parameter. Using up and down key to adjust the value or option in bottom
display. Once finished, press SET key momentarily to confirm and go to next
parameter.

Note 1. AH, Deviation high alarm; AL, Deviation low alarm:
Assuming measured humidity is PV and set humidity is H. When PV - H is
above AH, the built-in buzzer will turn on (deviation high alarm); when H – PV
is above AL, the built-in buzzer will turn on (deviation low alarm). User can
mute the alarm by momentarily pressing the Mute key. The alarm will remain
inactive until the process value moves out of the alarm zone. Both alarms are
deviation alarms, i.e., if AH = 20%, AL = 30%, and the Set Humidity (H) is 50%
RH, the alarm will be activated if the humidity is above 70% or below 20%. The
alarm function is suppressed at powering up or when the program is jumped
from one step to another step. It will be activated automatically once the
measured humidity enters the none-alarm zone (between H - AL and H + AH).
Note 2. Hy, Humidity Control Hysteresis Band, or Humidity Control Dead Band:
This parameter set up a dead band (between H - Hy and H + Hy) within which
either the humidifier or dehumidifier will not work. The minimum value for Hy is
0.5. The Hy value should not be too small if the system has sluggish response.
Otherwise, it may result in the humidifier and the dehumidifier working against
each other, wasting energy and causing oscillation.
Note 3. Hyd, Dehumidifier Hysteresis Band:
This is the differential band between turn on and turn off the dehumidifier. It is
set to the higher side of the dehumidifier set point (H + Hy). The dehumidifier
will turn on when humidity is above (H + HY + Hyd), and turn off when humidity
